Title: Improvements in and relating to the cooling of gas turbine blades and rotors
Inventor: TERRELL BASIL JOSEPH
IPC: F01D5/08
Filed: 1954-02-18
Abstract: 765,225. Cooling bladed turbine rotors. PARSONS & MARINE ENGINEERING TURBINE RESEARCH & DEVELOPMENT ASSOCIATION. Nov. 10, 1954 [Feb. 18, 1954], No. 4841/54. Class 110 (3). In a bladed turbine rotor, the rotor blades are formed with closed cavities which contain a quantity of some substance (such as sodium) which is liquid at least when the turbine is operating and constitutes the primary coolant. Heat is extracted from the rotor by causing a secondary coolant (such as water) to flow through the rotor near the blade roots. According to the invention, the secondary coolant flows through ducts in the rotor in the vicinity of the blade roots without coming into contact with the blade roots or blades. In Figs. 1 and 2 the blades are mounted in the rotor by their roots b and a series of longitudinal ducts c are formed beneath the periphery of the rotor, each duct lying between a pair of adjacent blade roots. Secondary coolant is supplied through the duct k and passes through radial ducts d to an annular space f which communicates with the ducts c. The coolant discharges into annular space g and through radial ducts e to the passage m. The roots of the blades may be copperplated to ensure good heat conductivity. In a second embodiment, Fig. 4, the rotor is of the overhung type and secondary coolant enters through a central duct k and passes through radial passages d which are bifurcated at their outer ends to longitudinal passages c between pairs of adjacent blade roots. The coolant then flows back through similar longitudinal and radial passages d<SP>1</SP> and discharges through passages m<SP>1</SP> parallel with the central passage k.

Patent GB-609750-A (GB)
Title: Improvements in or relating to the manufacture of interpolymers of styrene with polyhydric alcoholic mixed esters and of coating compositions obtained therefrom
IPC: C09D125/14
Filed: 1946-02-15
Abstract: Products suitable for use in paints, varnishes, insulating materials, adhesives, printing inks, moulding compositions and laminated materials are obtained by interpolymerizing styrene and one or more partially polymerized polyhydric alcoholic mixed esters containing conjugated triene drying oil fatty acid radicles.  The process may be carried out in aqueous emulsion or in solution; terpenes, e.g. mono- or di-cyclic a -terpenes, are preferred solvents and may be used alone, with further solvents, or they may be added during the course of the reaction.  In a modification, a part, e.g. 25 per cent, of the styrene is present initially and the remainder is added continuously or intermittently.  The mixed esters are partially polymerized esters or mixtures of esters of one or more polyhydric alcohols containing a mixture of fatty acid radicles of which a proportion are conjugated triene drying oil acid radicles and a proportion are unsaturated fatty acid radicles of other types, including the products of heat treating two or more fatty acid esters of polyhydric alcohols, one of which contains fully conjugated triene drying oil fatty acid radicles, e.g. tung and oiticica oils, alkyd resins formed from the condensation of one or more polyhydric alcohols with polybasic organic acids and a mixture of the different types of unsaturated fatty acids are also included. The preferred esters are formed from glycerol, penta-erythritol, mannitol and sorbitol and the fatty acids of drying, semi-drying and non-drying oils, or the acids of rosin or copal.  In examples: (1) a preheated mixture of blown linseed oil and raw tung oil was refluxed with styrene and xylene; (2) a preheated mixture of raw oiticica and linseed oils was refluxed with styrene, xylene and dipentene; (3) partially polymerized conjugated linseed oil, styrene and white spirit were refluxed together; (4) a tung-linseed stand oil was dispersed in an aqueous medium containing ammonia, turkey red oil, phenol, oleic acid and hydrogen peroxide, styrene was added and polymerization completed at 80 DEG  C.; (5) a xylene solution of an alkyd resin, prepared by heating together linseed and tung oil fatty acids, glycerine, pentaerythritol and phthalic anhydride, was refluxed with styrene and (6) a preheated mixture of heat-treated wood oil and dehydrated castor oil was refluxed with styrene and turpentine. The products were varnishes from which paints were obtained by addition of metallic driers and pigments.  Specifications 573,809, 573,835 and 580,912 are referred to.

Abstract: 451,514. Actuating controllers. BROOKS, R., St. Fillans, Moss Lane, Sale, and GRAY, W. T., Darroch, The Close, Altrincham, both in Cheshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Feb. 16, 1935, No. 5072. [Class 38 (iii)] Actuating-apparatus for a sequence switch comprises a supply of air under pressure which applies pressure to a liquid system under the control of an electromagnetically controlled air valve 2, the liquid acting through an electromagnetically controlled control valve 5 upon a plunger 6 coupled to the switch 7. The air pressure supply pipe 1 communicates through the valve 2 with a chamber 3 containing liquid 4. The valve 2, which in one position puts the supply pipe 1 in communication with the chamber 3 and in the other position vents the chamber, is controlled by an electromagnet 11. The control valve 5 is actuated by an electromagnet 15 which is rendered inoperative by the operation of a main current limit relay. The path of the liquid between the valve 5 and the cylinder 16 includes an orifice 17 which restricts the flow of liquid and ensures gradual movement of the plunger 6. Upon completion of the switching movement, the electromagnets 11, 15 are de-energized by limit switches on the switch, a bias, which may comprise a spring or a small plunger 19 acted on by the air pressure supply, becoming effective to return the switch to its initial position. This return movement is rendered -rapid by a relief valve 20 which opens when the chamber 3 is vented. The relief valve may be electromagnetically operated or controlled. The switch may be under the control of a manual controller having a plurality of positions arranged to initiate movement of the switch to corresponding positions, and such an arrangement is described with reference to Fig. 2 (not shown).

Title: Hydraulic pump or motor
IPC: F03C2/30
Filed: 1974-02-05
Abstract: 1424993 Reciprocating motors or pumps RELIANCE ELECTRIC CO 5 Feb 1974 [19 April 1973] 05197/74 Heading F1A An hydraulic reciprocating motor or pump has a plurality of slotted working chambers 22 each reciprocably receiving an elongate piston member 110, the latter being provided with a cylindrical recess 120 in which is disposed a roller 24 for co-operation with an undulating cam surface 74. In the motor shown, the working chambers 22 are formed as peripheral slots in a rotor 20 having a shaft 16 keyed thereto. The ends of the slots are closed by end housing sections 44, 48 between which is sandwiched a stator 40 on the inner surface of which is formed the cam surface 74. During operation the piston members 110 tend to turn in their slots about an axis parallel to the axis of the rotor. This rotation increases the contact pressure between each piston member and the sides of its slot at diagonally opposed regions 116, 118 and 112, 114, whereby sealing is improved. Liquid is alternately supplied to and exhausted from the slots through a ring of alternating inlet and outlet ports 90 and 92 in housing section 48, the ports coming into communication with the adjacent ends of the slots on rotation of the rotor. The ends of the piston members are provided with lubrication grooves 126, 128 which deliver hydraulic fluid to the roller recesses 120 and lubricating grooves 130 along the sides. Passages 100 passing axially through the rotor connect the ports 90, 92 to slots 102 in the housing section 44 or the end of rotor remote from the ports 90, 92 thereby to pressure balance the axial forces acting on the rotor.

Title: Improvements in or relating to Cathode Sputtering Apparatus
IPC: H01J37/34
Filed: 1967-02-03
Abstract: 1,169,991. Cathode sputtering apparatus. SIEMENS A. G. Feb. 3, 1967 [Feb. 4, 1966], No. 5253/67. Heading C7F. To obtain a predetermined mix of several constituents in a layer formed by sputtering, a cathode having a surface formed by separate areas of the constituents is used in a sputtering apparatus in which a plasma is produced other than by a potential between the cathode and anode. The surface areas of the constituents are so chosen that, with the rates of release of the individual constituents taken into account, the desired result is obtained. One constituent may be a disc, with the remaining constituents mounted on it in an array, or the cathode may comprise a disc divided into sectors and a rotatable body which is of one constituent and can be turned to selectively mask the constituents in the sectors of the disc. For example iron and nickel sectors may be masked by a nickel body, and the nickel body may be moved to adjust the composition of the iron-nickel alloy layer produced. The individual components of the cathode may be insulated from one another and placed at differing potentials, so that by connecting certain only of them as the cathode and placing the others at the potential of the anode, then changing the connections, laminated layers of differing composition can be produced. For example nickel-iron layers may be separated by layers of copper. The plasma in the sputtering apparatus may be produced by electron beams within the sputtering vessel. Alternatively the apparatus may comprise a cathode near one end of a slotted cylindrical anode which is surrounded by a container and penetrated, when in use, by a high-frequency magnetic field directed axially in relation to it, so that a ring discharge plasma is produced.

Title: Asphalt solid compositions and process of manufacture
IPC: C08L95/00
Filed: 1964-02-10
Abstract: A hard bituminous solid composition is made by mixing 8-30 wt per cent, based on the solid, of asphalt, with finely-divided solid, compressing to 80-98% of theoretical density, curing at 300-500 DEG F. for 4-80 hours, and then impregnating the surface of the solid composition with an asphalt and recuring at an elevated temperature. The solid material is any dry inorganic solid, e.g. earth, soil, cinder, expanded slag or clay, rock wool, steel wool, abrasives, coke, iron ore, diatomaceous earth, clay, silt, coal, asbestos, glass fibres, quartz, carbonate rocks and volcanic ash, alone or in combination, chlorite, talc, mica, haematite.  Clay soils ranging from almost 100% clay to low clay content may be used; if the structure is to be exposed to water, there should be less than 10% expanding clay.  An exemplified soil desirably contains 10-60% clay, the remainder being, e.g. silt and sand with or without gravel of diameter more than 2 mm.  The asphalt may be incorporated when molten with the preferably preheated finely-divided solid, the asphalt being introduced, e.g. as a low-pressure spray, atomized or foamed. Alternatively the asphalt may be cut-back with a volatile organic solvent boiling at 175-600 DEG  F., e.g. petroleum naphtha; the solution may contain 30-90% asphalt by weight.  The cut-back or molten asphalt preferably has viscosity of 20-100 Furol.  Emulsified asphalt may also be employed. A list of suitable asphalts, natural and artificially prepared, is given.  Minor amounts of natural and synthetic oils, resins, polymers, elastomers and rubbers may be mixed with the asphalt.  After mixing but before compaction the asphalt may be hardened by heating in air at e.g. 400 DEG  F.; alternatively, the rate of hardening may be lowered by blanketing the mixer with an inert gas.  The recuring temperature is preferably 250-500 DEG  C. In a modification of the process, the mixture is prehardened before compaction.

Title: Improvements in automatic press tools for straightening or bending
IPC: B21D3/10
Filed: 1941-05-01
Abstract: 549,989. Bending or straightening air screws &c. SALTNDERS, F. S. May 1, 1941, No. 5652. [Classes 83 (ii) and 83 (iv)] An automatic bending or straightening press comprises a block provided with a number of cylinders having a valve at the head of each, the valves being maintained open by mechanically actuated means and maintained closed by automatically-actuated means. The block 1 which may be attached at 25 to the ram of a press is provided with a number of oil containing cylinders 2 provided with pistons 3, the upper portions of which are cylindrical and the lower 7 rectangular and provided with arcuate recesses seating self-aligning elements 8 connected thereto by links 10 and provided with pads 9 of aluminium. The stroke of the pistons is limited by slots 11 in the side plates 5. The end portions engage end plates 4 and may be held out of operation when desired by pins 32 passing through holes 30 in the cylinders and pistons. The upper ends of the cylinders contain ball valves 15 which are closed by springs 16 but are normally held open by cam surfaces 20 on a slidable valve 18 which is normally pushed forward by an adjustable spring 22. The valve 18 is provided also with a number of fluted collars 19 and the valve chamber communicates by ports 27 and pipes 28 with bottles 24 containing compressed air. With the pistons normally in their lowered positions work of any shape is placed beneath the plungers which position themselves according to the shape of the work by displacing oil from the cylinders which passes through the flutes until all have aligned with the shape of the work. Movement of the ram then causes the plungers to rise equally and displace oil into pipes 28 to cause air pressure in the bottles 24 to rise whereupon the pressure acting on the valve 18 at 23 pushes the valve to the right to free the valves 15 and cause them to be closed by their springs 16 thereby rendering the pistons immovable relatively to each other so that bending commences. When sufficient bending is effected the operator releases the operating pedal or lever of the press and the ram commences to rise. The load being taken off the plungers the valve 18 is forced by the spring 22 to the left and the air pressure returns the oil to the cylinders until the plungers are again in their lowermost positions. In straightening a bent blade of an air screw the article 34 is placed on blocks 35, 36 arranged on opposite sides of the block 1.
